1	MICROBATCH	7.5	293	The purified protein at 30 mg/mL in 10 mM Tris pH 7, 100 mM NaCl, 2.5 mM 2-mercaptoethanol was incubated with 10 mM L-proline and 12% (v/v) DMSO on ice for 1 hr. Crystals were grown in a Terasaki Microbatch plate by mixing 1 uL the pre-mix with 1 uL of reservoir solution containing 0.25-0.4 M SrCl2, 15-20% (v/v) PEG3350 and 100 mM HEPES pH 7.5. The drops were covered with paraffin oil. Crystals were flash frozen in liquid nitrogen directly from the plate.
